+# Quay config tool
+
+The Quay config tool is a project to ease the setup, modification, and deployment of Red Hat Quay (sometimes referred to as Quay Enterprise).
+
+The project was built by [Sam Chow] in the summer of 2018.
+
+[Sam Chow]: https://github.com/blueish
+
+## Project Features
+* Isolated setup tool for creating the config
+* Ability to download config as a tarball
+* Ability to load your config from a tarball and modify it
+* When running on Kubernetes, allows you to deploy your changes to the current cluster and cycles all pods
+* When running on Kubernetes, allows you to modify the existing configuration
+
+
+## Project Layout
+- `conf/` - nginx/gunicorn configuration
+
+- `config_endpoints/` - backend flask endpoints for serving web and all other API endpoints
+
+- `config_util/` - utils used by api endpoints for accessing k8s, etc.
+
+- `config_util/config` - config providers used to manipulate the local config directory before being tarred, uploaded, etc.
+
+- `docs/` - some updated documentation on how to run the app in both a docker container and on kubernetes
+
+- `init/` - initial scripts/services started by the docker image
+
+- `js/` - all frontend javascript
+
+- `js/components` - mix of the old components ported over, and new components written for the config tool.
+(config-setup-app is the entrypoint of the frontend)
+
+- `js/core-config-setup` - The main component responsible for modification of the config.
+Holds most of the components that modify the configuration
+
+- `js/setup` - The modal component that covers the setup of the DB and SuperUser
+
+## Running the config tool
+Currently, the config tool is still being built alongside the regular Quay container, and is started with the `config` argument to the image.
+```bash
+docker run {quay-image} config
+```
+
+
+## Local development
+If you wish to work on it locally, there's a script in the base dir of quay:
+```bash
+./local-config-app.sh
+```
+Webpack is setup for hot reloading so the JS will be rebuilt if you're working on it.
+
+
+## Local development on kubernetes
+Assuming you're running on minikube, you can build the docker image with the minikube docker daemon:
+```bash
+eval $(minikube docker-env)
+docker built -t config-app . # run in quay dir, not quay/config_app
+```
+
+You'll now have to create the namespace, config secret (and optionally the quay-enterprise app and nodeport)
+- [quay-enterprise-namespace.yml](files/quay-enterprise-namespace.yml)
+- [quay-enterprise-config-secret.yml](files/quay-enterprise-config-secret.yml)
+- [quay-enterprise-redis.yml](files/quay-enterprise-redis.yml)
+
+(Optional, use if you're testing the deployment feature on kube)
+- [quay-enterprise-app-rc.yml](files/quay-enterprise-app-rc.yml)
+- [quay-enterprise-service-nodeport.yml](files/quay-enterprise-service-nodeport.yml)
+
+And the following for the config-tool
+- [config-tool-service-nodeport.yml](docs/k8s_templates/config-tool-service-nodeport.yml)
+- [config-tool-serviceaccount.yml](docs/k8s_templates/config-tool-serviceaccount.yml)
+- [config-tool-servicetoken-role.yml](docs/k8s_templates/config-tool-servicetoken-role.yml)
+- [config-tool-servicetoken-role-binding.yml](docs/k8s_templates/config-tool-servicetoken-role-binding.yml)
+- [qe-config-tool.yml](docs/k8s_templates/qe-config-tool.yml)
+(Note: right now the config tool template uses the tag `config-tool:latest`, which will be the image you created in the minikube docker)
+
+Apply all of these onto the cluster
+```bash
+kubectl apply -f <name-of-file>
+```
+
+You can get minikube to route you to the services:
+```bash
+minikube service quay-enterprise-config-tool -n quay-enterprise
+```
+
+It should open up on your default browser.
+
+(Note: The config tool is only available through SSL and self-signs certs on startup, so you'll have to use https://\<route>
+and pass through the warning on your browser to access it.)
+
+When you make changes to the app, you'll have to rebuild the image and cycle the deployment:
+```bash
+kubectl scale deploy --replicas=0 quay-enterprise-config-tool -n quay-enterprise
+kubectl scale deploy --replicas=1 quay-enterprise-config-tool -n quay-enterprise
+```
